Making a sled dog harness (silent)

While this is the bare minimum and it doesn't show all the steps, it's enough to see the general structure and with some measurements, you could make your own.

You want the tension to be on their shoulders, not their neck. You'll know if it hits the neck too much, they will make you know and probably caugh as well.

They only showed the start of the padding but it's important, you don't want to hurt your dog. I would do a small tan leather tube filled with straw or whatnot.
